XSLT 2.0 actually says that it's an error to generate two output files with
the same URI, and Saxon 8.3 attempts to check for this, rather than having
one simply overwrite the other.

But you're essentially asking for some way of generating unique filenames.
There are plenty of ways of doing this. I usually use something like
href="chap{position()}".
